, SPECIFICATION forming part of Letters Patent No. 376,986 dated January24,19 8,

Application filed July 8, 1857. Serial Nr 243,712. "(No model.)

like letters on the drawings representing like parts.

This invention has for its object to improve the construction ofelevated railways adapted for suspended cars; and it consists in thecombinatiou, with the main vertical uprights, the foundation-beams, andfoundation brace-rods for the vertical uprights, of two truss-framessupported by the vertical uprights upon sup-' porting-beams, brace-rodsfor said supportingbeams, and stay-bars and binding-rods connecting thetwo truss-frames, all as will be hereinafter more fullydescribed, andpointed out in the claims at the end of this specification.

Figure 1 shows in side elevation a section of an elevated railwaystructure embodying this invention, it showing two vertical uprights A,two of said key-blocks being herein shown.

The lower ends of the uprights A A enter mortises cut in afoundation-beam, A which beam is secured to a suitable base of masonryor equivalent in any suitable manner, as by bolts 2. I

Brace-rods A are placed in position bearing against the uprights A A andthe foundation-beam A round the uprights A' A and the foundationbeam A,which strips are joined by stay-rods 4., having suitable turn-buckles,ing the said rods. 7

A collar, A surrounds the uprights A A just at or above the points wherethe strips 3 5, for tighten- Metallic strips 3 partially surand thebrace-bars A are connected with said uprights, which,.it will beunderstood, is substantially at the surface'of the ground, asit isdesired'that the entire foundation for the uprights should be beneaththe surface of the ground.

Asupporting-beam, B, is mortised at'its' cen- I 7 ter to receive theupper end of the uprights A A, said supporting-beam being bracedby twobrace-bars, B, bearing against the under side of the supporting-beam andagainst the uprights A A, said brace-bars being held .in fixed positionby suitable bolts. Two supporting-beams, B,'are placed beneathandparallel with the supporting-beam B,'i't bein'g secured to thebrace-bars B by suitable bolts.

Two truss-frames rest one upon each'end of thesupporting-beams B B",each of said trussframes consisting of two horizontal parallel beams, G0, connected by cross-bars cc,'which bear against the blocks a, securedto said horizontal beam 0; alsoby the binding-rodsc which are tightenedby turn-buckles c",the said binding-rods entering the blocks c,orpassing through said bloclis' into the beams O O. The

beam 0. of each truss-frame rests upon the top of the supporting-beam B,and the beam G'isheld up against the under side of the supporting-beamsB". The two beams G G are also joined by binding-rods d, which aretightened by turn-buckles d, a vertical supporting-rod, v

9o, vals apart, and also each corresponding pair ot beams O O of thetruss-frames are joined by the binding'rods i, there preferably being.

four sueh'bindingrods between each pair of cross-bars ff, saidbinding-rods being loosely" connected with the corresponding beams of'each truss at a point near the junction of the cross-bars f fand thebeams, the opposite ends of' the binding-rods i passing inward toward acentral point between each pair of crossbars and beams and fastened to aring, i, by suitable nuts, so that'by turning the said nuts within thering the binding-rods may. be tightened. The'railwaystructure may bethus made of any suitable length, the vertical uprights or supportsbeing placed at short dis tances apart and the brace-frames, constructedas described and united to each other, being supported by said uprights.

It will be seen that by the construction of the uprights and theirfoundation beams and braces, and also by the construction of thetruss-frames and their supporting-beams and braces mounted upon thesupports, they are all made with a 'view to obtain the greatest amountof strength and durability in as simple a manner as possible.

The rails for the suspended cars are fixed to the beams c 0 one abovethe other, to thereby form two tracks, one at each side of the verticalsupportingbeams.

I claim-- 1. In an elevated railway structure, the main verticalsupports and trussframes supported by them, said main vertical supportsconsisting of two uprights, A A, having a narrow space between themgradually increasing in width toward the lower ends, and key-blocksfitted into and between the uprights, combined with the foundationbeamand brace-rods, substantially as and for the purpose specified.

2. In an elevated railway structure, the main vertical supports, eachconsisting of two uprights placed side by side, but separated some whatat their lower ends, combined with the foundation-beam A bracebars A andbinding-rods, and means for securing the foundatiou-beam rigidly inposition, substantially as described.

3. In an'elevated railway structure, the main vertical supports, eachconsisting of two uprights placed side by side, but separated somewhatat their lower ends, and key-blocks A, and bolts passing through theuprights, combined with the foundation-beam A brace-bars A andbinding-rods, and means for securing the foundation-beam rigidly inposition, sub stantially as described.

4. In an elevated railway structure, the main vertical supports andtheir foundation beams and braces, combined with the supporting beams B13 and braces therefor, and the trussframes supported upon the beams B Bthe cross-bar and binding-rods forming component parts of thetruss-frames,and the cross-bars and binding-rods for joining the saidtruss-frames, substantially as described.

5. In an elevated railway structure, the main vertical supports andtheir foundation beams and braces, combined with the supportingbeams B Band braces therefor, and the trussframes supported upon the beams 13 B,the crossbars and binding-rods forming component parts of thetruss-frames, cross-bar ff, the binding-rods i, and the ring 2',forjoiuing lhetwo trussframes,substantial1y asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

BENJAMIN F. HAMILTON.
